Not bad, but not the best,
By A Customer
This review is from: Sip: Understanding the Session Initiation Protocol (Artech House Telecommunications Library) (Hardcover)
I found the book useful as a backup reference to the spec, but not the best explanation I have seen. It was at times slightly confusing, and found that I was constantly referring back to the SIP overview in D. Collins "Carrier Grade Voice over IP" (which is very well written). From an education perspective, it was a little like a dictionary for SIP that explained concepts such as what a given header was for, but gave little info on how it is used, or what the industry is doing.There were some call flows, but they were sparse with a few mistakes. Further, they were either very base, or very comprehensive, and did not cover many of the questions I had. In summary, if you are looking for a readable reference to help with the not so reader friendly RFC, this is pretty good. For learning how SIP is being imlemented beyond basic call handling, keep looking. As an option, also look at the book by Collins noted above. It is a good overview reference, and tries to address where the industry is moving from an implementation perspective

Just an introduction to the SIP RFC,
By A Customer
This review is from: Sip: Understanding the Session Initiation Protocol (Artech House Telecommunications Library) (Hardcover)
This book simply summarizes some of the SIP RFC into more user-friendly english. It consists mostly of lists of SIP headers and error codes, lifted from the RFC. There is no sample code or discussion of SIP applications or architecture. Of course, the RFC is pretty hefty, so this book has been a useful introduction. I still use the RFC as my real reference, though, because there are some minor discrepancies between the book and the RFC, such as some error code names.

OK but could be much better written,
By A Customer
This review is from: Sip: Understanding the Session Initiation Protocol (Artech House Telecommunications Library) (Hardcover)
The information contains in the book makes it a pretty good primer on SIP. The organization of the book and its content is very good. The language and ways in which the author explains certain things are confusing. I think the author should be able to do a much better job in explaining things. I often find myself having to re-read certain explainations twice and much carefully when I feel I shouldn't have to -- the topics are not complicated but not well explained. Someone like Doug Comer or Richard Stevens would probably be able to make it a much easier read.
